Now that his own contract extension is set, Green Bay Packers’ G-M Ted Thompson says he plans to do the same for head coach Mike McCarthy.  The Packers announced a multi-year extension for Thompson yesterday.  No other details were released — but according to media reports, past signing trends indicate that the 61-year-old Thompson is now signed through 2018.  He and McCarthy were both given extensions after the Super Bowl season of 2010, which extended their deals to 2015.  That means McCarthy still has two years left on his current package.  McCarthy is the only coach Thompson has hired in his nine-plus years as G-M.  McCarthy came on board in 2006.  The Packers have gone 92-62-and-1 during Thompson’s tenure.  He appeared tired in February at the N-F-L Scouting Combine — and he missed the owners’ meetings in March with an undisclosed health issue.  But now, Thompson says he feels much better — and he still enjoys the chase of finding overlooked talent. The Packers have had 13 undrafted free agents on their roster over the past four years — the third-highest in the N-F-L.
